Our Stage 2 for the E36 M3 and MZ3 is a building block to Stages 3, 4, and 5. All of the following stages require the parts from Stage 2. In this Package we supply a aFe Euro Cold Air Intake, TMS 3.5" HFM with adapter, "24lb" Bosch fuel injectors, associated installation hardware and instructions, and TMS-exclusive Stage 2 software (co-developed with Jim Conforti).

The aFe Euro intake is designed for a 3.5" HFM and includes a heat shield to block warm air from the engine compartment. The aFe intake uses an oiled cotton air filter for maximum air flow and excellent filtration. The kit is supplied complete with heat shield, intake tube, sealing materials, hardware, and install instructions.

The HFM is 3.5 inches in diameter - a half-inch larger than the stock HFM. We selected the HFM from the Porsche 911 (993) because of its superior metering capability over the Euro M3 or 540 HFM. This HFM comes with a custom wiring harness for a seamless install and full compatibility with the Siemens DME and Conforit software. The beauty of this HFM is that it reads airflow far more accurately than less-expensive other HFMs on the market. Imagine the data stream on a strip of tape 3 feet long. A stock or Euro/540 HFM will read that data 50 times for the length of the tape. The Porsche HFM will read the same data 300 times in that same distance. That extra metering allows us to fine-tune the software to make the engine more responsive, smoother, and produce more power!

We found that the stock fuel injectors on the S52 engine were at their maximum capacity with the larger HFM and intake. To prevent dangerous lean conditions we spec'd out a larger set of Bosch fuel injectors (24lb/hour or 25.5lb at the BMW-spec 3.5bar of pressure). The software was recalibrated to match the larger fuel flow.

The rest of this Package is made up of a HFM adapter to work with the stock throttle body boot (Samco silicone boot optional), installation hardware, HFM wiring harness, and installation instructions. As a Package, installation time for the typical do-it-yourselfer would be 3-4 hours.

Related Upgrades -
Underdrive Power Pulley Kit - Underdriving means each component is moving slower which requires less power. The saved horsepower is put back to the engine where it transfers to power at the wheels. Power gains are typically 10hp at the wheels.
Exhaust - Borla or Corsa cat-back muffler for more performance, lighter weight, and a more-aggressive sound. Expect a gain of 5whp with either of these exhausts.
